So, I completely missed a huge story just over a week ago. Most of the world did, in fact. I was personally kicking myself when I finally caught it.

It's about options, specifically on gold, silver, and bond ETFs. Not the type of story that generates headlines.

And you may think it sounds boring at first — but I promise you the implications are monumental.

Before I get ahead of myself, let’s back up for a second. The more liquid a stock is, the more options expirations it gets.

With the least liquid, you get the standard monthly close. A bit more liquid, weekly Fridays. More than that, Wednesday and Friday too. Even more, Monday, Wednesday, and Friday.

Or, of course, we can have options that expire every single day.

As a refresher, an option is a contract that gives you the right (not the obligation) to buy or sell something at a set price (the "strike") by a set date. A call is the right to buy at that price. A put is the right to sell at that price. The price you pay for that right is the premium.

Now, those options expiring every day is something you've probably heard about already. It’s the territory of those "0DTE" (zero days to expiration) degenerates you hear about on the news. Those young gamblers.

The broad indexes and ETFs have options expiring every day. The names you’d expect, like SPX (the S&P 500), SPY (the S&P 500 ETF proxy), QQQ (the tech-heavy Nasdaq ETF proxy), and IWM (the small-cap index ETF proxy) are all there.

You can open a position in the morning for the same day, betting the level or price will move to a certain place, and it’ll disappear in the afternoon.

Who cares? Well, we all do. Or at least we all should.

An option expiring every day isn't just business for 0DTE traders or options experts. 0DTE wags the underlying's tail a lot of the time, and increasingly so since 2022.

It's one of the dark arts, which can get super complicated, very math-heavy, and quite grueling — so I love it.

But I'll get to what I mean by that in a second.

On August 12, the SEC approved a rule letting GLD, SLV, and TLT join the daily-expiration complex. Gold, silver, and long bonds, all cleared for the full five-day treatment.

We can now hang out together and day trade gold until we grow old together. (Kidding! But we could.)

GLD's already there. Its new Thursday expiration is trading right now, today, with real volume behind it. SLV and TLT are cleared for the exact same thing; they just haven't been listed yet.

The exchange just has to actually list the series. And at this point, that's closer to paperwork than policy. Could happen any day.

So here's how I want to do this…

First, I’ll tell you everything that I think happens once SLV and TLT actually catch up to GLD, along with why I think that.

Then we’ll dig into the overall shift that this is part of — because this is just the newest chapter of a much bigger story.

Why This Matters

SPX went through this exact transition back in 2022, when Cboe finished rolling out the daily complex on the index. It kicked off an argument that still hasn't fully settled: Does trading options that expire in hours, instead of weeks, make the underlying more volatile or less?

You've probably heard the "more" case, because it's the one that makes for better headlines. Retail gamblers, a market getting more casino-like by the day, dealers scrambling to hedge and dragging the tape around behind them.

There's good research behind this version too, not just vibes. A jump in 0DTE trading volume has been tied to measurably higher realized volatility.

But there's also a growing pile of research on the other side, and I fall into this camp personally because it’s nuanced in the correct ways.

Researchers looking at S&P 500 options found that on days with 0DTE trading, realized volatility actually came in lower, not higher — a modest but real dampening effect. Cboe's own research group has run this analysis more than once and keeps landing on the same thing…

0DTE flow tends to run fairly balanced between puts and calls, dealer net gamma stays small most of the time, and the mechanism people assume is destabilizing spends most of its life doing the opposite.

In plain English: Trading more means the people selling and buying the options have more reason to buy and sell regularly, which creates a stabilizing effect.

But truthfully, both camps are right, just about different days. When 0DTE positioning is roughly balanced, dealer hedging calms the tape down. When it's lopsided — everyone piling into puts on a selloff, say — the same mechanism flips and starts amplifying instead.

Average it across a big enough sample, and it looks stabilizing. The tail days look like something else.

Now, all of that research is about the S&P 500. GLD, SLV, and TLT are smaller ecosystems, with a different user base — more macro hedgers, fewer retail degenerates — and a different hedging mix. There's no guarantee the SPX balance holds here.

That's not a reason to ignore the mechanism, though. It's a reason to actually watch what happens instead of assuming it.

Dealers, Makers, and Gamma

Okay, now for the dark arts part, or the reason I think any of the above.

When you buy an option, someone sold it to you. Usually a market maker or dealer, whoever's on the other side of that trade professionally.

That dealer doesn't want directional risk. They want to collect the spread and go home flat, so they hedge: buy or sell the actual underlying to offset the option they just sold.

How much they need to hold shifts as price moves. And that sensitivity, or how fast the hedge has to change, is gamma. Acceleration by any other name.

It's biggest right at the money, when the strike price (the price you're locked into if you exercise the option) sits near where the stock, ETF, or index is actually trading — and right before expiration, which is exactly why 0DTE gets treated as a different animal, even though structurally it's the same contract on its last day alive.

Gamma's the one everybody already half-knows. And it’s the thing professional floor traders know inside out and use because it’s been so powerful since options were introduced in the ‘70s. 

But the two that actually define the 0DTE world are charm and vanna, the new guys on the block.

Delta is how much an option's price moves for every $1 move in the underlying. A 0.50 delta option gains or loses about $0.50 for every dollar the stock, ETF, or index moves. Charm and vanna are both just ways delta changes.

Charm is delta decay, or how much an option's delta shifts purely because time passed, with price sitting completely still.

Every option has some charm, but it's a footnote on something with a month left to live.

Compress that same option down to hours and charm stops being a footnote: a 0.50-delta option can be halfway to zero by the afternoon on time alone, no price move required. And the dealer on the other side has to keep buying or selling the underlying just to stay flat with it.

That's why "unexplained" drift tends to show up like clockwork in the final hour or two of a heavy 0DTE session. It's really just an hourglass flipped upside down.

Vanna is the other one, or how delta shifts when implied vol moves, not price.

It's why a single sentence out of the Fed can move a hedge book before the underlying's even reacted.

Vanna isn't unique to 0DTE the way that charm is. But 0DTE is where it does the most damage, because there's no runway left to absorb the shock. A volatility spike on an option with three weeks to expiry gets smoothed out over three weeks. A vol spike on an option with three hours to expiry gets hedged in three hours, all at once.

Put those two together, and that's the real case behind everything I predicted above. It’s not that gamma exists; gamma always existed. It’s that charm and vanna — the greeks that decide how fast a dealer has to move — both get sharper the closer you are to zero days.

Every extra expiration day is another day where some slice of the book is living inside that window.

A New Mechanical Layer

Now, for a long time, gold, silver, and long bonds moved for one reason: whatever was actually happening in the world.

Inflation prints, Fed decisions, dollar strength, geopolitical fear. Slow assets, moved by slow, fundamental forces, with options sitting quietly on top of the price action rather than inside it.

SPX stopped being that kind of market first.

Once it had options expiring every single day, the index picked up a second, mechanical layer underneath the fundamental one — a layer where the size of the move on any given day depends not just on the news, but on where dealer gamma, charm, and vanna happen to be sitting that morning.

Same headline, different day, different-sized reaction, because the plumbing underneath it is different.

That's the reality daily expirations are dragging gold, silver, and long bonds into.

On top of the macro story.

The Fed will still be the reason TLT moves. But increasingly, how fast it moves, how sharp the reversal is, and whether it pins near a round number into the close…

That's going to depend on this second, mechanical layer that almost nobody trading these three funds has had to think about before, because it barely existed for them until this month.

Now for the actual numbers. And since only GLD is actually live, I'm treating it differently than TLT and SLV.

GLD's numbers are today's real evidence. TLT's and SLV's numbers are the "before" picture — what their books look like right now, heading into a change that hasn't happened yet, so there's something to compare against once it does.

Start with gross exposure — call-side plus put-side, ignoring sign — because that tells you how much machinery each fund is carrying, regardless of which way it leans.

TLT's gross gamma is around $62 million. SLV's is about $13 million. GLD's is about $3 million. TLT is carrying by far the biggest gross machine of the three, and it's the one still waiting on its Tuesday and Thursday.

Gross isn't net, though, and net is what a dealer actually has to hedge.

TLT's calls and puts nearly cancel out — $32 million against $30 million. So despite the biggest gross book, its net gamma is only about $2 million. SLV's gamma is smaller in gross terms but less balanced, landing around $4.6 million net. GLD, the live one, sits small and balanced too, around $1.5 million net.

Charm has a similar shape. TLT's net charm is the steepest of the three — around negative $116 million. SLV isn't far behind, around negative $100 million. GLD's charm is nearly flat, around negative $2 million, because its call-side and put-side charm largely cancel out — worth noting, since GLD is the one actually running the daily complex right now and its charm still isn't dramatic. That's evidence against the loudest version of this story, not really for it.

Vanna is where SLV stands out. Its net vanna is running north of $162 million — bigger than TLT's $89 million, bigger than GLD's $24 million — and built differently too. In GLD and TLT, put-side vanna pulls hard against the calls and knocks the net number down. In SLV, the puts barely register, so almost the whole $162 million comes through net.

Everything above — the gamma, the charm, the vanna — is what’s called open-interest-based exposure. It's a snapshot of where positioning sits, updated on a schedule, and built on modeling assumptions about who's short what.

It's not a live read of any dealer's actual book, and it doesn't predict that price has to move a certain way. It tells you where hedging pressure can matter, not that it must. Very important distinction.

Even GLD's numbers today are still mostly the ordinary September and January listings, not the new Thursday specifically, which is hours old.

The real signal, for all three, is what happens to these numbers over the coming weeks as volume actually finds its way into the new dates.

What I Think Happens

When SLV and TLT actually get their Tuesday and Thursday listed, here's what I expect…

TLT gets mechanical

It's already carrying the biggest gross gamma of the three (around $62 million) and the steepest charm drain (around negative $116 million).

Once that's resetting five days a week instead of three, expect more "why did this drift for no reason into the close" behavior… more pinning near big open-interest strikes on expiration days… and Fed-day moves that show up faster and snap back harder, because there's more often a fresh, at-the-money options book sitting there to catch the shock.

SLV is the one that squeezes

Smaller gross machine than TLT, but by far the most lopsided positioning. Its $162 million of net vanna is almost entirely on the call side with nothing offsetting it. And it has the highest implied vol of the three by a wide margin, around 51% at two days out. (Implied vol is the market's forecast of how much a stock is likely to swing, annualized. The higher the number, the more movement is priced in.)

That combination produces fast, ugly, out-of-nowhere moves.

If one of these three has a real gamma squeeze in the next few months, my money's on SLV. (Hint: starting mid-2025 into January of this year, it already did.)

GLD keeps being boring, and that's the point

It's already running the full daily complex today, and its charm and vanna numbers are still small and balanced.

If "more expirations equals more chaos" were simply true on its face, GLD should already be showing it. But it isn't.

That's evidence that a balanced book stays balanced, and it's the baseline TLT and SLV get measured against if they don't behave the way I'm predicting.

Zoom out, and expect this to keep happening

This is the same walk SPX took in 2022, just smaller and in a different asset class.

Once a fund joins the daily complex, more of its trading activity migrates toward same-day and next-day contracts. Closing-hour volume becomes a bigger share of the day. And the options market stops sitting quietly on top of the "real" price and starts becoming part of how that price actually gets discovered.

I'd expect that to show up in TLT and SLV gradually, not on day one, but over the weeks and months after positioning actually migrates into the new days.

That leaves the question…

What Do I Do Now?

Nothing. Absolutely nothing.

I'm not being cute. There's no trade here today… no “this-changes-everything” portfolio move… no reason to touch your gold, silver, or bond position over a rule that's still finishing its rollout.

What I am saying is that this is a story to check back on. I’ll also be covering it extensively.

But just watch GLD if you feel so inclined, since it's the one actually live. If it keeps behaving like a small, balanced book, that's the theory holding.

Watch SLV and TLT's listing calendars for when Tuesday and Thursday actually show up, not when the rule says they're allowed to.

Once they do, I’ll come back to these same numbers — gross gamma, net gamma, net charm, net vanna — and see whether TLT starts drifting into closes the way I'm predicting, and whether SLV's already-lopsided vanna book turns into an actual squeeze.

And keep the causality straight while you wait.

Rates move because macro reprices, and the options market can amplify or smooth that move, not manufacture it from nothing.

Same for gold and silver.

When TLT eventually gets twitchy around an FOMC statement, the Fed will have caused that. The options complex will just decide how fast the twitch propagates — once it's actually plugged in.
